✱ NOTE: The term, Electric Vehicle (EV), is used in this Guide to refer to either a vehicle that plugs into an electric power source to charge and store electric energy in a vehicle battery, or to a Fuel Cell Electric Vehicle. For those that plug in, the term includes both plug-in hybrid EVs (PHEV), and battery EV (BEV). The term does not include conventional hybrids, as they do not plug into an electric power source.
! IMPORTANT: To determine which EVs receive support, visit the EV Make/Model Support Reference The GO Plan is required.
✱ NOTE: Do you have a use case/feature request for your EVs?
The Sustainability Product Management Team wants to hear from you! We work hard to improve our products and your feedback is important to us. Please contact your Reseller.
Starting in Fleet Management Application version 8.0, there are automatically populated built-in groups that allow you to quickly find and filter on EVs in features, reports, and exception rules.
✱ NOTE: For a vehicle’s electric powertrain to be detected, the EV must be supported, and, in the case of a BEV or PHEV, it must have charged at least once.
Found under the Asset Information group, the Powertrain and Fuel Type group automatically classifies electric vehicles (EV) based on their unique powertrain types:
Assets can be manually added or removed from the groups if they are not properly displayed in their respective group.
For supported EVs, the live Map displays the current battery charge % and indicates whether the vehicle is charging, driving, or stopped.

Get notified when an EV becomes at risk of not having sufficient charge to complete routes without stopping to charge, which is a high productivity loss. This rule will trigger when the electric vehicle (EV) battery charge % (State of Charge) drops below the configured value.
When an EV returns to a lot/depot with sufficiently low charge, it is time to plug in. This rule is useful for plug-in reminders and identifying which EVs need to be prioritized for charging.
This rule will trigger when EVs exit a charging zone of the specified type(s) while its battery charge is below the configured value. This is useful for identifying EVs that:
Important Information and Tips:
This rule will trigger when the EV battery is charged to the configured value. This is useful to indicate when the EV’s charging plug can be provided to another EV, or when it is important to know when the EV is ready for use.
This rule will trigger when an Electric Vehicle (EV) stops (ignition off) in a zone that has known charging stations, and does not start charging within the configured amount of time. This is to allow for time after the vehicle stops for the vehicle to get plugged in and start charging.
For when EVs shouldn’t be plugged in, such as situations where there are more EVs than plugs, and the charge level remains sufficient to cover needs, it’s possible to enable this rule to be triggered only when the EV has a battery charge % (state of charge) less than the configured value.
This is useful for identifying:

Below is a simplified list of EV-relevant fields in this report:
Field | Description |
Distance | Total distance traveled on all energy sources. |
Electric Energy Used | Total electric energy used during ignition on, expressed in either kilowatt hour (kWh) or watt hour (Wh). Wh is used when the Electric Energy Economy Measurement unit is set to Wh/km or Wh/mile; otherwise kWh is used. ✱ NOTE: Energy added to the battery from all non-charging sources — regenerative braking, driving down a hill, fuel engine charging in a hybrid — is subtracted from Electric Energy Used. If energy is added to the battery faster than it is consumed, the value will be negative. |
Fuel Economy | This is displayed when the vehicle travels exclusively on fuel (electric energy used = 0); otherwise the field remains blank. |
Electric Energy Economy | This is Electric Energy Used divided by Distance. This is displayed when the vehicle travels exclusively on electric energy (fuel used = 0); otherwise the field remains blank. It is a primary indicator of vehicle electric energy efficiency and performance. ✱ NOTE: See Electric Energy Economy Measurement to change the measurement unit. Similar to Electric Energy Used, if energy is added to the battery faster than it is consumed, the value will be negative. |
Total Fuel and Electric Energy Economy | This is a single comparable value across all your vehicles and displayed for every vehicle. If electric energy is used, it is converted to the equivalent in fuel. This converted value is then added to the Fuel Used to calculate this combined Economy value. If electric energy is not used, this value is the same as Fuel Economy. Units = The equivalent of the selected fuel economy measurement. To learn how we convert electric energy to fuel, please refer to the note below. ✱ NOTE: Similar to Electric Energy Used, if energy is added to the battery faster than it is consumed, the value will be negative. |
% Electric Energy of Total | Calculation of electric energy used (%), based on all electric and fuel energy usage. To learn how we convert electric energy to fuel, please refer to the note below. ✱ NOTE: When Electric Energy Used is negative, this value may exceed 100%. |
Both electricity and fuel are forms of energy. This report performs a conversion of electric energy to the equivalent in fuel to calculate the Total Fuel and Electric Energy Economy, and the % of Electric Energy of Total. For Battery Electric Vehicles (BEV), the equivalent in gasoline fuel is converted. For PHEV, the units convert to the same fuel type that’s used by the vehicle when the fuel type is reliably available.
The United States Environmental Protection Agency (EPA) and the United States Department of Transportation (DOT) have adopted the standard conversion and states that 1 US Gallon of Gasoline is equivalent to 33.7 kWh of electric energy. Additionally, the United States Department of Energy Alternative Fuels Data Center defines 1 US Gallon of Diesel as having 113% of the energy of 1 US Gallon of Gasoline.
Using these baseline conversions, including standard volume conversions to Liters and Imperial Gallons, we can convert electric energy to the equivalent in fuel.
Similar to Fuel Economy Measurement, the Electric Energy Economy Measurement allows users to display measurements in the desired units.
To change the measurement unit, follow the steps below:
1 | In the Fleet Management Application, click the username in the top right corner of the screen and select Options. |
2 | Under the Main Settings tab, choose the desired measurement unit located next to Electric Energy Economy Measurement. |
3 | Click Save. |
✱ NOTE: The “-e” attached to L and MPG indicates that the unit converts electric energy to the equivalent in either liters or gallons of fuel. For BEVs, electric energy is converted into the equivalent in gasoline. For PHEVs, electric energy is converted into the same fuel type used by the vehicle as detected by the Telematics Device. The conversion requires the Telematics Device to accurately detect the fuel type, otherwise, the electric energy is converted to the fuel equivalent in gasoline.
Unit | Description |
km/kWh | For a primarily EV fleet, this helps you understand how much distance you can cover based on the battery energy — measured in kWh. |
L-e/100 km | The best choice for a primarily non-EV fleet when the preferred fuel economy measurement is L/100 km. ✱ NOTE: This converts electric energy into the fuel equivalent (in liters) to present a value in familiar units. For BEVs, electric energy is converted into the equivalent in gasoline. For PHEVs, electric energy is converted into the same fuel type used by the vehicle — detected by the Telematics Device. The conversion requires the Telematics Device to accurately detect the fuel type; otherwise, the electric energy is converted to the fuel equivalent in gasoline. |
km/L-e | The best choice for a primarily non-EV fleet when the preferred fuel economy measurement is km/L. ✱ NOTE: This converts electric energy into the fuel equivalent (in liters) to present a value in familiar units. For BEVs, electric energy is converted into the equivalent in gasoline. For PHEVs, electric energy is converted into the same fuel type used by the vehicle — detected by the Telematics Device. The conversion requires the Telematics Device to accurately detect the fuel type; otherwise, the electric energy is converted to the fuel equivalent in gasoline. |
kWh/100 km Wh/km kWh/km | For a primarily EV fleet, this helps you understand how much energy is used / needed for a specified distance. |
Unit | Description |
mi/kWh | For a primarily EV fleet, this helps you understand how much distance you can cover based on the battery energy — measured in kWh. |
MPG-e (US) MPG-e (Imp) | The best choice for a primarily non-EV fleet when the preferred fuel economy measurement is MPG. ✱ NOTE: This converts electric energy into gallons equivalent of fuel to present a value in familiar units. For BEVs, electric energy is converted into the equivalent in gasoline. For PHEVs, electric energy is converted into the same fuel type used by the vehicle — detected by the Telematics Device. The conversion requires the Telematics Device to accurately detect the fuel type; otherwise, the electric energy is converted to the fuel equivalent in gasoline. |
kWh/100 miles Wh/mi kWh/mile | For a primarily EV fleet, this helps you understand how much energy is used / needed for a specified distance. |
✱ NOTE: Electric Energy Economy is currently based on distance. In some cases, EVs operate in a stationary position for long periods of time, and idle. In these cases, it’s better to calculate Electric Energy Economy over time rather than distance, such as kWh/hour. Use the Electric Energy Used value and report time period to calculate this value.
The Fuel and EV Energy Usage page displays the electric energy and fuel usage by vehicle. Similar to Fuel used, the value for Electric Energy used is displayed under the corresponding vehicle. The list view also displays Total Fuel and Electric Energy Economy for each vehicle, as described in Report Fields — EV Specific Meanings. When both fuel and EV energy are used, clicking on a row gives you the choice to either view the Fill-Ups or EV Charging Report.
Includes all fields listed in Report Fields — EV Specific Meanings, except for % Electric Energy of Total.
Includes all fields listed in Report Fields — EV Specific Meanings.
The EV Charging Report is the EV equivalent of the Fill-Ups Report used for fuel. This report provides information about the electric power and energy consumed when vehicles plug in to charge.
Power, expressed in kilowatts (kW) or watts (W), is the rate at which electric energy is transferred into the vehicle for charging. The lower the power value, the longer the vehicle takes to charge.
Energy, expressed in kilowatt hours (kWh) or watt hours (Wh), is the total volume of power transferred or used over an hour.

! IMPORTANT: The report fields are populated differently for the following sections in the List, Report, and Advanced report views: start and end dates, duration, and the start and end battery charge %.
Charge Event — Report Tab of Report & Advanced
A Charge Event is recorded from when charging starts (power > 0 W) to when it stops (power = 0 W). During a single stop, there may be multiple Charge Events, if a managed charging, power sharing technology, or manual plug sharing is employed. In this report, each row of data corresponds to a single Charge Event.
Charge Session — List and Summary Tab of Report & Advanced
A Charge Session groups all Charge Events that occur during a single stop. In this report, each row of data corresponds to a single Charge Session. This is intended as a more readable format — especially when managed charging, power sharing or plug sharing is employed.
Field | Description |
Start Date | In the Report and Advanced Report tab, this is the date and start time of the Charge event. In the List, and Report & Advanced Summary tab, this is the date and start time of the Charge Session — the start of the first charge event during a single stop. |
End Date | In the Report and Advanced Report tab, this is the date and end time of the Charge Event. In the List, and Report & Advanced Summary tab, this is the date and end time of the Charge Session — the end of last charge event during a single stop. |
Odometer | The vehicle’s odometer at the charging time. |
Location | The street address of the charging location. When Personal Mode is applied, this will be blank. |
Zones | If the location is within one or more Zone, the names of the Zones are displayed. When Personal Mode is applied, this will be blank. |
Zone Types | If any Zone has one or more Type, the name of each Zone Type is displayed. When Personal Mode is applied, this will be blank. |
Start Charge % | In the Report and Advanced Report tab, this is the battery charge % remaining at the start of the Charge Event. In the List, and Report & Advanced Summary tab, this is the battery charge % remaining at the start of the Charge Session — the start of the first charge event during a single stop. |
End Charge % | In the Report and Advanced Report tab, this is the battery charge % remaining at the end of the Charge Event. In the List, and Report & Advanced Summary tab, this is the battery charge % remaining at the end of the Charge Session — the end of the last charge event during a single stop. |
Energy Added | The total electric energy added, expressed in either kilowatt-hour (kWh) or watt hour (Wh). Wh is used when Electric Energy Economy Measurement unit is chosen as Wh/km or Wh/mile; otherwise kWh is used. |
Max Power | During a Charge Event or Charge Session, the power typically fluctuates. The maximum value is the best indicator of the sustained power found throughout. The maximum value is also the best indicator of the EV contribution to additional billing charges resulting from excessive power demand, and for being aware of the capacity requirements for EV charging. Wh is used when Electric Energy Economy Measurement unit is chosen as Wh/km or Wh/mile; otherwise kWh is used. |
Current | This is either AC (Alternating Current) or DC (Direct Current). If you want both at once, check out the band by that name, AC/DC. |
AC Voltage | The Alternating Current voltage. |
Electric Energy Economy | The equivalent concept to Fuel Economy in the Fill-Ups Report. This is the amount of energy consumed over the total distance traveled since the end of the previous Charge Event / Charge Session to this one. See Electric Energy Economy Measurement to change the measurement unit. This is not populated for PHEVs if fuel was consumed within the report’s time period. |
✱ NOTE: For those in North America who want to display charging as SAE Level 1 (120 V AC), SAE Level 2 (~240 V AC), or SAE Level 3 (DC), use the Current and AC Voltage values to extend the report. |

EV Battery State of Health is a new report that calculates and displays the change in usable stored energy capacity over the lifetime of your Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs), for the EV’s high voltage (HV) battery. It is available in Beta as of Fleet Management Application version 8.0.
✱ NOTE: Usable capacity versus actual capacity: Usable energy (kWh) capacity is that which the vehicle makes accessible for storage and vehicle operations, which may be different from what is physically available (actual).
EV HV batteries degrade over time and under different conditions. The health of the battery over time is a new unknown impacting lifecycle projections, range and residual value. Use this report to gain visibility on the health of your EV battery.
The current methodology uses historic data communicated by the vehicle to detect original usable energy capacity and current energy capacity. In the future, we will explore communicating values directly from the EV’s manufacturer / BMS (Battery Management System), which are not commonly reported in a standardized way.
! IMPORTANT: To determine which EVs receive support, visit the EV Make/Model Support Reference. The GO Plan is required.
Key Questions | Answers |
How healthy are my EV (high voltage (HV)) batteries today, across all my EVs? | Run the EV Battery Health report, for the most recent month, and view health %, which are a function of current detected capacity compared to original detected capacity. |
| Run the EV Battery Health, for the time period ‘Forever’ (which starts January 1, 2021) and see at a glance month over month usable capacity changes per vehicle. |
Original usable capacity is the detected capacity of the battery when the EV was first manufactured. It’s used as the comparison point for health. Battery capacity is detected monthly using a 90-day rolling average, and these detected battery capacities are compared to original capacity. The current methodology uses historic data communicated by the vehicle to detect original usable energy capacity.
✱ NOTE: Usable capacity versus actual capacity: Usable energy (kWh) capacity is that which the vehicle makes accessible for storage and vehicle operations, which may be different from what is physically available (actual).
For accuracy and consistency, this is crowdsourced from the make, model, year, and trim of EVs across the Fleet Management Application customer base, when VIN decoding is available. These capacity values are compared with a single original capacity value for all EVs of the same make, model, year, and trim.
To accurately detect the original capacity, input data is collected over approximately the first year of an EV’s life, from a set of the same make, model, year, and trim. Original capacity values will change month to month during the first year of an EV’s life as they become more accurate. The most recent and accurate values replace previously reported original capacity values for consistency and accuracy. For more information, see Why are the original capacity values in the report changing month over month?

The Battery Electric Vehicle (BEV) Range Capability Report calculates the range capability for your BEVs - that is, the average distance your vehicles can travel on a full charge, based on your fleet’s operating conditions and historic energy consumption.
Making full use of the range limits of your BEVs and reducing productivity loss incurred by unplanned charging stops is a new challenge as fleets add more and more electric vehicles. There are many different standards to calculate range capability, and some might be derived from calculations based on operating conditions that do not match your own fleet’s. The operating conditions that impact your range capability include seasonal temperature changes, speed (urban slower speeds vs. long distance higher speeds), terrain (hilly vs. flat terrain), cargo weight, heating and cooling the vehicle cabin, and driver behavior.
The BEV Range Capability report seeks to address that need and gap, calculating the range that your BEVs are capable of doing based on the energy consumption during historic calendar months.
! IMPORTANT: Which vehicles are included in the BEV Range Capability report?
Only vehicles detected as Battery Electric Vehicles (BEVs) will be included in the report.
Vehicles detected as BEVs are automatically displayed within the Battery Electric Vehicle group under Asset Information > Asset Type > Electric or Hybrid Plug-in > Battery Electric Vehicle. Note that you can manually add or remove vehicles from this group if any vehicles are missing or incorrectly classified.
To determine which EVs are supported, refer to the EV Make/Model Support Reference spreadsheet.

Asset | The asset that the range capability calculation applies to. |
Group | The Groups that the asset belongs to. |
Make | The vehicle’s make, determined from the vehicle’s VIN. If the VIN was not detected accurately, or if VIN decoding is pending, then this field will be blank. ✱ NOTE: User-contributed VINs via the Fleet Management Application are not used. |
Model | The vehicle’s model, determined from the vehicle’s VIN. If the VIN was not detected accurately, or if VIN decoding is pending, then this field will be blank. ✱ NOTE: User-contributed VINs via the Fleet Management Application are not used. |
Year | The vehicle’s model year, determined from the vehicle’s VIN. If the VIN was not detected accurately, or if VIN decoding is pending, then this field will be blank. ✱ NOTE: User-contributed VINs via the Fleet Management Application are not used. Additionally, for some VIN formats, the year is not communicated in a standardized way and might not be available. |
Detection Date | The date and time of the Range Capability determination. This is done monthly on the first day of the month. |
Detected Range Capability | The vehicle’s range capability in the user’s set measurement units (kilometers or miles). This value represents the average distance that the vehicle is capable of traveling on a full battery charge, based on the average energy consumption observed over the distance traveled during the Period. The data elements that are used to calculate Range Capability include:
|
Detected Electric Energy Economy | The electric energy economy (in the user’s selected units) achieved by this vehicle during the Period. Answers: “How much distance was this BEV getting per kWh of usable battery capacity?” |
Detected Usable Battery Capacity | The usable energy capacity (in kWh), detected during the Period, which the vehicle makes accessible for storage and vehicle operations. This value may be different from the physical battery capacity (actual). This value represents the mean of a normal distribution of various calculated battery capacity values and has an associated confidence interval of 90%. See the Usable Detected Capacity for more information. |
! IMPORTANT: Why are the distance or energy values in this report different from other reports of the same duration?
Not all trips may be used by this report to determine range capability. The range capability algorithm excludes outlier trips that may introduce inaccuracies to the results.
Here are a few possible reasons:
Applies to:
The root cause for all missing values is missing usable original capacity values, which are currently auto-detected from EVs. The auto-detection process depends on a number of factors:
To accurately detect the original capacity, input data is used from a set of the same make, model, year and trim EVs, when it is available via VIN decoding. The data is collected over approximately the first year of the vehicle’s use. Month over month during that year period, original capacity can therefore change and updated for improved accuracy.
To provide a highly accurate determination of the original capacity of a given EV, data to determine the original capacity is collected from a sufficiently large sample of EVs sharing the same make, model, year, when available via VIN decoding, and trim. The sample is then averaged, with a 90% confidence interval available. Since original capacity is an average (mean), there will be cases, especially in the early life of an EV, whereby the detected capacity can be higher than the make, model, year, when available via VIN decoding, and trim original capacity determination. For these cases, we cap the EV battery health calculation at 100% to indicate that battery health is detected as the best it can be.
